Polar Integration is the integration of a polar function. Polar functions are expressed in terms of "theta", the angle around the origin, and "r" the distance from the the origin. The integration of such a function is finding the arc area between the curve and the origin.

Polar Integration is a form of polar calculus, that is the calculus of polar functions. Although it may seem trivial It is useful for finding the area beween the origin and the curve, and with analytic geometry can be extremely useful.
